GeForce 940M vs GeForce GT 430

Intro

Compare those specs to the GeForce GT 430, which features core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 430 should theoretically be a lot superior to the GeForce 940M overall. (explain)

GeForce GT 430		28800 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The GeForce 940M should be much (approximately 130%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 14528 (130%)

Pixel Rate

The GeForce 940M should be much (more or less 206%) better at full screen anti-aliasing than the GeForce GT 430, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 940M		8576 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 5776 (206%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
